[JDEV] Sparse considerations about server status

Like I posted earlier I need more specifics to investigate this. Having clients
build in safeguards is ridiculous! This would be a server bug by far if no
bounce is happening and it is actually getting lost somehow. It has high
priority in my books, but I need info, debug logs, incoming/outgoing XML for
both parties involved, and anything else that will help.
